Abstract

A liquid crystal display device includes a display unit including a plurality of gate lines and a plurality of signal lines, a scanning unit that sequentially scans lines corresponding to the plurality of signal lines, a memory circuit that stores video data based on a scanning signal from the scanning unit, and a selection circuit, to which signals formed of two values are supplied, that selects one of the signals formed of the two values based on the video data stored in the memory circuit and supplies the selected signal to one of the plurality of the signal lines as a video signal.
